Hi to all,

Can peltier can be connected to PWM fan pins ? Please help in this.

The fan PWM pins are limited to 1.5A max continuous current. Most peltier units draw more current than that.

Hi dc42,

Thanks for reply. Is there any alternative for that like using any electronic components?

You could use an SSR or mosfet switch to switch the current to the Peltier device, and connect the inputs of the SSR or mosfet switch to a fan output.

can you get a circuit design for the same? or can you tell which mosfet i have to use?
